Tele Vue went beyond the Barlow concept to achieve the goal of a compact, high power, fully corrected image amplifier. The Powermate consists of a negative doublet plus a positive "pupil-correcting" doublet lens. This 4-element system provides the magnifying function of a Barlow without its limitations by restoring the field rays back to their original direction, as if the Powermate were not there. The result is a pure magnification increase. Vignetting, edge field aberrations and pupil movement are minimized. In addition to full multi-coating, Tele Vue Powermates include safety undercuts where practical on the chrome barrel, captive lock screws that can?t fall out, and filter threads. Powermates are ideal for high magnification CCD astrophotography or film imaging. The Powermate is not a Barlow so the Tele Vue Panoptic-Barlow interface is not needed.

Warranty
This product is serviced and supported by its manufacturer according to the terms and conditions included in the packaged product. Orion's limited warranty does not apply. Please contact the manufacturer directly for technical support.

Warning

Please note this product was not designed or intended by the manufacturer for use by a child 12 years of age or younger.

Compression ring

Instead of a single thumb screw locking the eyepiece in place, a brass ring compressed by a thumb screw secures the eyepiece. This spreads clamping force over a larger area of the eyepiece's barrel, which provides a better connection. The compression ring also prevents the tip of the thumb screw from producing unsightly scratches and divots on the eyepiece barrel.

Warranty

This warranty gives you specific legal rights. It is not intended to remove or restrict your other legal rights under applicable local consumer law; your state or national statutory consumer rights governing the sale of consumer goods remain fully applicable.

Tele Vue Panoptic telescope eyepieces set the standard for wide field optical performance. They are fully multi-coated and feature a sharp, high-contrast image across their 68anddeg; field of view. The optics are housed in an exquisitely crafted body.

Tele Vue Nagler telescope eyepieces offer an 82anddeg; spacewalk view of the night sky. But a large field of view isn't all these eyepieces are known for. Their sharpness, contrast, and brightness is unparalleled in the industry.

The Tele Vue Ethos line of telescope eyepieces provide a stunningly wide field of view combined with optical performance that is unmatched. 100anddeg; field of view (110anddeg; for the 3.7mm) provides the observer with a beautiful vista into space.

For cleaning the lenses in your telescope or binocular, the Orion Microfiber Optics Cleaning Cloth lifts dirt, fingerprints, water and oil from surface without scratching, streaking or smearing delicate lens surfaces. The cloth is machine washable.
